As Internet has been spreading and popularizing, lots of industries of he society are changing their industries to be compatible to the internet. In other works may companies are investing for Electronic Commerce to change their industries....so there are lots of company to introduce electronic commerce in his industrial fields and this kind of tendency is increasing now, because electronic commerce has a lot of advantages this kind of tendency has been trying in the shipping industrial fields... so we an find lots of marine electronic commerce sites in the internet by a searching engine. these sites insist their site is real portal in the shipping field.. But actually their sites just e-commericalize a field or some fields of shipping, So they cann't insist their site is a real portal site But in this kind of tendency, real shipping portal site will be made someday but not so long.. so we want to show contents and strategy real shipping portal site should possess by comparison and generalization with existing shipping portal sites.

There is no study that application of the maturity using H.B.C and H.S.C. Also activation energy has different values according to the cement, admixture and water-cement ratio. Therefore to make accurate explanation for the effect of temperature on concrete strength development properties, it is necessary that activation energy value according to the kind of cement is reviewed. This study compares and estimates equivalent age using activation energy value obtained by this experiment and Freiesleben activation energy value with compressive strength of concrete. As the result of this study, activation energy value obtained by this study has more accurate explanation of temperature's influence on concrete strength development than Freiesleben activation energy value.

The composition of fatty acid and amino acid for Seong-ge-al(sea urchin) were analysed by the automatic analyser. There are two kind of samples such as raw and saited, fermented one. The results obtained are as follows. 1. In the general composition, crude protein, crude lipid and ash as 15.8%, 3.5% and 2.2%, respectively. The raw sample showed pH 5.6 value. 2. In case of amino acid, it contained 17 different kind of amino acids. Among them, a lot of glutamic acid, aspartic acid, arginine, glycine and valine were contained. 3. In case of fermentation period, threonine, histidine, lysine and arginine were increased a little bit. 4. In case of fatty acid, it contained 13 different kind of fatty acids. Among them, a lot of palmitic acid, behnic acid, linoleic acid and arachidonic acid were contained.

The purpose of this study was to provide the basic informations of disposable medical clothes and develop new disposable medical clothes which are not caused environmental pollutions. The staffs of Yuhan-Kimberly and doctors, nurses and personnel of four general hospitals in Seoul were interviewed individually in order to collect useful data of disposable clothes. Also the samples of disposable medical clothes were examined. The materials, designs, size of potential market and actual consumption conditions of disposable medical clothes were found out. New disposable medical clothes were made after having considered all the aspects examined above. Two kind of medical gowns and caps, a kind of medical apron, three kinds of patient robes and a kind of patient cap were made of Korean traditional paper with specific functions instead of nonwoven polypropylene fabric.

The purpose of this study is to provide a guide for selection of oral hygiene devices for nations and establishing valid indication of recently popularized water jet. The author has divided 36 persons into general, orthodontic, periodontal patients according to their oral hygiene state, and then evaluated the degree or decrease in plaque indices and gingival bleeding indices. The obtained results were as follows. 1. When both manual toothbrush and water jet were used together by three kind of patients, significant decreases in plaque index were observed in all patients, after 4 weeks compared with ordinary toothbrushing only(p<0.05). 2. When both oral hygiene devices were used together by three kind of patients, significant decreases in gingival bleeding index were observed in all patients after 4 weeks compared with ordinary toothbrushing only(p<0.05). 3. Singificant differences of the average gingival bleeding index & plaque index among three kind of patients were observed(p<0.05). 4. Therefore, it is concluded that for effective oral hygiene care. water jet can be recommendable to general patients, especially to orthodontic or periodontal patients.

The main focus of this paper is on the study of the radiation effect upon the electrical property of a A-Kind insulator which is one of the organic insulators. The varnished cloth is so typical of the A-Kind insulators as to be selected for a sample. AC and Impluse voltage is applied to the variable Gamma ray irradiated dose samples with the constant time duration and the dielectric breakdown voltage are measured from the sample. The experimental data of the dielectric breakdown voltage are considerably decreased. The above conclusion is useful for the selection and application of the orgainc insulators under the irradiation effects.

This study attempts to suggest the requisites for selecting the neighboring fisheries of the same kind related to the calculation of aquaculture fisheries loss stipulated in the article 62 of enforcement ordinance of fisheries law. First of all, the requisites for the same kind of aquaculture fisheries are legally evident. The more important requisites are the factors for the neighboring fisheries of aquaculture fisheries. Here the factors we must consider are the same oceanic environment, the same fisheries management, and the same productivity of fisherman. In conclusion, the best way of selecting neighboring fisheries is picking up the adjacent fishery to the fishery because the factor of the same oceanic environment is the most important in determining the productivity of fisheries.

Objective: The purpose of this study is to investigate the mechanism and effect of moxibustion with salt objectively, to be used as the quantitative data through the measurement of temperature, and to grasp the thermodynamic characteristics of moxibustion with salt. Methods: We have selected of the moxibustion with salt of indirect moxibustion. We make a comparative study of the thermodynamic characteristics of moxibustion with salt as a kind of the 4 salt. We examined combustion times, temperatures, temperature gradients in each period during a combustion of moxa. Results: 1. We make out that it is not significantly change the time of thermal conduction of moxibustion with salt as a kind of 4 salt. 2. The heating period of Refined Salt was long and that of Sun-dried Salt was a short time respectively. The heating period of maximum tamperature is high Sun-dried Salt, Mechanical Salt and Refined Salt orderly. Maximun heating speed in the heating period was $0.151{\sim}0.184^{\circ}C/sec$ and at the same tendency of the maximum temperature in the heating period. 3. The retaining period was shorter than the heating period respectively, that is 15~24% of the combustion time of in the heating period. We make out that it is not significantly different the time of the retaining period as a kind of 4 salt. The mean temperature of retaining period was $43.2{\sim}48.1^{\circ}C$, that was extraordinarily high temperature. 4. We make out that it is not significantly different the time of the cooling period as a kind of 4 salt. The cooling period was measured 223~233sec. Beacuse the same density and size of moxa combustion was made an experiment. 5. The effective combustion time of Refined Salt is longer(259sec) than that of Sun-dried Salt(173sec). It is significantly different the time of the combustion time as a kind of 4 salt. 6. It is significantly different the Sample deviation of the combustion time as a kind of 4 salt because of the water content of the 4 salt individually. Conclusions: As the base on this study, we obtained the conclusion as the follows. The salt of moxibustion with salt was fitted for Sun-dried Salt due to making to Mechanical Salt recently. The Refined Salt is composition rate to another and small size comparatively. So It was fitted for the salt of moxibustion with salt. It is necessary to study continuously about the more suitable moxibustion with salt and quantitative analysis about the moxibustion with salt.

Using Schensted Insertion and Deletion algorithm for shifted rim hook tableaux described in [7], we construct Schensted algorithm for shifted rim hook tableaux. This give us the combinatorial proof for the orthogonality of the second kind for the spin characters of $\tilde{S}n$.
